A cut of 20 minutes on the journey time will save commuters more time and increase the attractiveness of Bristol and in the same upgrade, Swindon should come down to the 45 minute journey time mark (this is a modest estimation based on the speed and length of the route, under 45 minutes would be possible with a recasting of the timetable).

You could leave a workplace in London, travel to Swindon and be in your home within the hour, what an opportunity!

Notes : Metroland was the name given to the areas of the expanded Metropolitan Railway north west of London which was heavily tied and influenced by housebuilding and essentially created the modern definition of commuting.
